Abstract

Suggested is the use of a mixture, comprising (a) fatty acid alkyl esters according to general formula (I) R¹COO—R² (I) in which R¹CO represents an unsaturated acyl radical having 16 to 22 carbon atoms and 1, 2 or 3 double bonds, and R² represents a C₁-C₄ alkyl radical; (b) at least two non-ionic sugar or polyol surfactants, and optionally (c) polyols as an additive for agricultural compositions.

Claims

(a) fatty acid alkyl esters according to general formula (I)

R¹COO—

R² 

 

(I)

where R¹CO represents an unsaturated acyl radical having 16 to 22 carbon atoms and 1, 2 or 3 double bonds, and R² represents a C₁-C₄ alkyl radical,

(b) at least two surfactants selected from the group consisting of non-ionic sugar surfactants and surfactants derived from polyols, and optionally

(c) polyols.

2. The mixture of claim 1, wherein said fatty acid alkyl esters are derived from (high oleic) sunflower oil, soy oil, canola oil or olive oil.

3. The mixture of claim 1, wherein said fatty acid alkyl esters are ethyl esters.

4. The mixture of claim 1, wherein said nonionic sugar surfactants or surfactants derived from polyols represent alkyl polyglycosides, sorbitan esters, polyglycerol esters and/or their mixtures.

5. The mixture of claim 1, wherein said polyols represent glucose or sorbitol.

6. The mixture of claim 1, further comprising a silicone, wherein the mixture comprises

(a) 40 to 70% b.w. fatty acid alkyl esters according to formula (I);

wherein the mixture adds optionally together with water to 100% b.w.

7. An agricultural composition comprising biocides and the mixture of claim 1.

8. The composition according to claim 7, wherein said biocides represent herbicides, fungicides, insecticides or their mixtures.

9. The composition according to claim 7, wherein the composition is used as a tank-mix adjuvant for pesticides formulations.

10. A method for improving the growth and health of plants and crops wherein the plants and crops are treated with a composition of claim 7.

17. The mixture of claim 2, further comprising a silicone, wherein the mixture comprises

(a) 40 to 70% b.w. fatty acid alkyl esters according to formula (I);

(b) 10 to 20% b.w. non-ionic sugar surfactants or surfactants derived from polyols; and

optionally

(c) 0 to 15% b.w. polyols; and
